Abstract
The utility model relates to a capacitor belongs to capacitor technical field, including insulating cover, upper cover, rivet, explosion -proof block, electrode, casing, on cover the symmetry and be provided with upper cover wiring hole, the last explosion -proof block who answers with upper cover wiring pore pair that is provided with of explosion -proof block sees the drive -by -wire, pass through rivet connection between insulating cover, upper cover, the explosion -proof block, the upper cover edge sets up decurrent turn -ups, the border is provided with inward recess on the casing, the turn -ups can the block to the recess. Design block structure between upper cover and the casing of this technical scheme through at capacitor, when producing high temperature causing in the twinkling of an eye increased pressure when capacitor in, pressure can in time be dredged outward to capacitor through groove structure, the problem of avoiding direct capacitor internal pressure can't in time discharge and lead to the fact capacitor to explode, the practical value who has profitable technological effect and showing.
Description
Technical field
The utility model relates to a kind of capacitor, belongs to capacitor technology field.
Background technology
Current capacitor is at power electronics, the field such as communications service and rail transport is widely used, along with the development of scientific and technological level, power capacitor relies on its good electrician's performance and high reliability, become and promote above-mentioned industry field and to update indispensable electronic component, but film capacitor in use, running into overtension, frequency is high, during the extreme conditions such as temperature is high, the heat that in capacitor, electrode produces can not shed in time, and then generation temperature and pressure sharply raises in capacitor, finally cause capacitor explodes, time serious, can be short-circuited between positive and negative electrode in capacitor, cause electric power system fault, therefore the structure of capacitor how is improved, make its explosion-proof performance better, become the focus of field of capacitor manufacture research and development.
Summary of the invention
For solving problems of the prior art, the utility model provides the better capacitor of a kind of explosion-proof effect, and concrete technical scheme is as follows:
A kind of capacitor, comprise insulating case, upper cover, rivet, explosion-proof block, electrode, housing, cover on described and be symmetrically arranged with upper cover wiring hole, described explosion-proof block is provided with the explosion-proof block corresponding with upper cover wiring hole and sees line traffic control, rivet interlacement is passed through between described insulating case, upper cover, explosion-proof block, described cover rim arranges downward flange, and described housing upper edge is provided with inside groove, and described flange can be engaged on groove.
As the improvement of technique scheme, the side near upper cover on described explosion-proof block offers oval groove, and be provided with hardboard between described upper cover and explosion-proof block, described hardboard retrains by oval groove.
As the improvement of technique scheme, described hardboard offers the through hole running through plate face, described rivet is fixedly connected with insulating case through after through hole and upper cover wiring hole.
As the improvement of technique scheme, between described hardboard and upper cover, be provided with packing ring.
Technique scheme by designing a kind of snap-in structure between the upper cover and housing of capacitor, when producing high temperature in capacitor and causing instantaneous pressure to increase, pressure can be dredged in time by groove structure outside capacitor, avoid explicit capacitor internal pressure cannot discharge the problem causing capacitor explodes in time, there is useful technique effect and significant practical value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of capacitor of the utility model.
Embodiment
As shown in Figure 1, the utility model provides and comprises insulating case 10, upper cover 20, rivet 50, explosion-proof block 60, electrode 70, housing 80, described upper cover 20 is symmetrically arranged with upper cover wiring hole 21, described explosion-proof block 60 is provided with the explosion-proof block corresponding with upper cover wiring hole 21 and sees line traffic control 62, connected by rivet 50 between described insulating case 10, upper cover 20, explosion-proof block 60, described upper cover 20 edge arranges downward flange 23, described housing 80 upper edge is provided with inside groove 81, and described flange 23 can be engaged on groove 81.Technique scheme by designing a kind of snap-in structure between the upper cover 20 and housing 80 of capacitor, when producing high temperature in capacitor and causing instantaneous pressure to increase, pressure can be dredged in time by groove structure outside capacitor, avoids explicit capacitor internal pressure cannot discharge the problem causing capacitor explodes in time.
Further, side near upper cover 20 on explosion-proof block offers oval groove 61, hardboard 40 is provided with between described upper cover 20 and explosion-proof block 60, described hardboard 40 retrains by oval groove 61, further, hardboard 40 offers the through hole 41 running through plate face, described rivet 50 is fixedly connected with insulating case 10 through after through hole 41 and upper cover wiring hole 21, wherein the effect of hardboard 40 is fixed rivet 50, and, after capacitor Long-Time Service, may deformation be there is in intraware, rivet 50 is caused to produce distortion, retrained by hardboard 40 pairs of rivets 50, rivet 50 twisting resistance is spread out, extend capacitor useful life.
Further, packing ring 30 is provided with between hardboard 40 and upper cover 20, its middle washer 30 can adopt soft material to make, the effect of its middle washer 30 has two, can be combined with rivet 50 on the one hand to improve and effect is gripped to hardboard 40, flexible support can be formed between upper cover 20 and hardboard 40 on the other hand, guarantee the stability of structure.
